Abstract
A method for providing feedback during ligament insertion in knee joint orthopedic surgeries includes providing an imaging device providing knee joint articular surface geometry data, providing a position measuring device providing distal ligament insertion sites, providing a strain measuring device providing ligament reference strain, providing a drive system providing a prescribed kinematic path for the knee joint and providing an adaptive migration application. The adaptive migration application receives inputs including the knee joint articular surface geometry data, the distal ligament insertion sites, the ligament reference strain and the prescribed kinematic path for the knee joint and generates outputs including sets of isotonic, hypertonic and hypotonic points representing proximal insertion sites of a ligament fiber associated with prescribed distal ligament insertion sites.
